How to program aan app

I’ve bought powerplugs (WiFi) from . In my opinion much better than the zwave alternatives. my homey has a terrible zware range . I wonder if I can program an app for these devices? How and were can I get tutorials to learn this. I am not an experienced programmer. But not unfamiliar with it, although with oldfashioned tools. Who can put me on the right direction? Thanks in advance.
